Load measuring device e.g. load cell, for train to measure force between pantograph and catenary system of electric line, has sensor fixed on face of elastic element, so that face is subjected to constant deformation on length of sensor

摘要

The device (101) has an elastic element (105) inserted between elements (102, 103) e.g. plates, where the elements receive loads. Optical fiber sensors are fixed on a surface of the elastic element to measure the deformation of the elastic element. One of the sensors is fixed on the face of the elastic element turned toward one of the elements, so that the face is subjected to constant deformation on the length of the sensors when the load is applied to the element.
